\subsection{3D Split-Screen Using Polarized Glasses}
Instead of using a 3D television to display images in 3D for a single person, it is possible to display two different 2D images on the same screen by the use of Polarized Glasses \citep{3d_splitscreen}. One of the key actors is Sony with their SimulView Technology \citep{simulView} that makes it possible for two people to play a game on a single screen but with two different images (see Figure \ref{fig:simulView}).

\begin{itemize}
\item \textbf{Input/output}: Has no input. Screen, which is filtered through the glasses, is the output. The maximum number of concurrent players is two.
\item \textbf{Social}: Even though players are centred around the same screen, they don't necessarily see the same image. This can be used both to stimulate a social behaviour, or to make a distance between the players.
\item \textbf{Market penetration}: According to \citep{3d_sales}, 65.59 million 3D televisions have been shipped in 2011 and 2012 combined.
\end{itemize}

\underline{Assessing The Applicability}

The technology fits well with the idea of asymmetric information. The players look at the same screen but are shown two different images (individual information). It is easy to imagine how this could be used in a multiplayer context. The specific hardware needed is a 3D television and polarized glasses. However, due to the inherent nature of 3D, which displays two images instead of one, there is a limit of only two people using it simultaneously.
